Disciplined and determined, you've probably climbed the career ladder, or are at least making progress. You made some awesome friends. You have lots of reasons to feel proud of yourself.
So, why aren't you happier? You're not setting aside enough time to play! Yeah, you're not a little kid anymore. But adults should play, too. Go to a theme park.
Run around and swim at the beach. Play games at an arcade or on the playground. Join a sports team. Just be silly and laugh with friends. Fun is totally underrated, especially with you, Capricorn!
